Those that submit products through Google Merchant Center to be shown on Google Shopping/Google Product Search can now submit feedback to Google for issues and feature requests.

Ronald from the Google team posted a thread at the Google Merchant Help forum asking for feedback. He said:

Merchants have already taken the time to submit some feedback to Google, so why don’t you do the same?

Also, Ronald noted in another thread that removing the file or metatag you added to your website as part of the verification process will result in losing your “verified” status and will need to go through the verification and claiming process again.

So submit your feedback!
